Abstract of Talk:
Rotor and Stator high shear mixing equipment have been installed in a wide range of industries and applications. Very little has been published in regards to determining rotor/stator design that is most effective to size reduce particles, create an emulsion or scaling up from Pilot to Production. Many vendors will scale up High Shear Mixing equipment by maintaining a constant tip speed of the rotor and keep the shear gap between the rotor and stator constant to ensure a constant Shear Rate. Shear Rate calculations are a theoretical calculation and have proven to be an in-accurate method for scale up as it does not take into consideration the change in flow (velocity of the fluid) or changes in the dimensions of the rotor/stator “tooth” geometry.

Quadro has developed a Slot Velocity Theory taking into consideration the change in flow rate to ensure accurate and predictability scale-up for Emulsion Applications. More recent studies completed and published by Merck have expanded the Slot Velocity Theory and developed a Slot Event Model to incorporate the critical geometric parameters by considering the frequency and probability of a particle size reduction from Pilot to Production Scale.

Additional details within the seminar will include detailing rotor/stator designs that are most effective to achieving the smallest droplet (Emulsions) and Particle Size Reduction of a solid taking into consideration:

  • Single stage vs. Multi-Stage design rotor/stator
  • Rotor/Stator Design
  • Tip Speed
  • Liquid Flow rate

Please register no later than Tuesday September 29 at 5:00 PM
